Classification of pulse dust collector
Circular pulse dust collector
The cylindrical low-pressure direct injection pulse bag dust collector is a newly developed product. This series of products has low preparation resistance, high dust removal efficiency, easy operation, simple maintenance, low air source pressure, low noise, and long life (can operate continuously and normally).
Two years) small size. The average scraper ash discharge method of the dust collector reduces the height of the equipment and improves the ash discharge effect. It has been widely used in grain, metallurgy, building materials, medicine and other industries.
Square and circular pulse dust collector
A special square pulse bag filter is directly connected to the solenoid valve to reduce damage to the solenoid valve diaphragm and work stably and reliably. High-tech famous products with novel structure and compact technology. Double air inlets, flexible process layout and small floor space.
High dust removal efficiency (≥99.9%). Filter bags can be selected according to user needs, including ultra-fine, temperature-resistant, moisture-resistant, and anti-static.
How does a pulse dust collector work？
The reverse pulse dust collector is a dry high-efficiency dust collector. It is a dust removal equipment that uses filter bags made of organic and inorganic fibers to filter out solid particles in dust-containing gases.
For dust above 2 μm, its efficiency can reach 99.9%, with low cost, simple management and convenient maintenance.
Working principle of Pulse dust collector：
Dust-containing gas enters the bag dust collector. Under the action of diffusion, gravity, collision, etc., dust within a certain particle size range will adhere to the dust receiving surface of the filter bag, forming a dust cake.
Clean air passes through the filter bag and is discharged from the body, achieving separate air and dust to achieve the purpose of purifying the air. Over time, the thicker the dust cake accumulates, the higher the resistance of the dust collector, resulting in a decrease in dust collector efficiency.
In order to ensure the normal operation of the system, dust cleaning must be carried out. The purpose of dust cleaning is to remove dust adhered to the surface of the filter bag so that the dust layer remains within a certain range and the system operating resistance fluctuates within a certain range.
How to choose pulse dust collector?
The selection of reverse pulse jet filter is mainly considered from the aspects of process, environmental protection and economic cost.
The following points should be considered when selecting a jet bag filter:
- Dust characteristics;
- Process requirements;
- Installation environment;
- Operation and maintenance methods;
- Existing resources, etc.
Selecting a pulse dust collector is a comprehensive consideration process:
- Select the filtration wind speed according to the dust characteristics; select the filtration area according to the air volume and filtration wind speed required by the process equipment;
- Choose a square or round pulse jet type dust collector according to the installation environment. The basic parameters of the dust collector are determined by the filtration area and shape;
- According to the characteristics of the dust, choose whether the material of the filter material is ordinary needle felt or peritoneal needle felt, whether it needs to be resistant to high temperature, acid and alkali, and whether the filter bag should be round, flat or oval;
- According to the operation and maintenance requirements and the installation environment, determine whether the bag changing method is up or down;
- According to process requirements and the installation environment, determine the location of the air inlet and outlet, the location of the ash discharge port, etc.
- The efficiency of reverse pulse filters can generally reach 99.9%, so there is generally no need to consider it when choosing.
More suggestions for Pulse dust collector selection：
The selection of reverse pulse filter is a critical step in meeting process requirements, but the design of the entire air network should not be ignored.
The quality of the air network design is directly related to the energy consumption, working capacity and dust removal efficiency of the dust removal system.
- If the dust inlet concentration exceeds 15 g/m3, it is generally necessary to pre-purify or reduce the filtration wind speed. It is recommended that the filtration wind speed of the dust collector in the crushing section is less than 2 m/min.
- At normal temperature, peritoneal filter material can be used for dust with a particle size ≤1 μm or with high moisture content. It is not suitable for dust with larger particle size and too different particle size distribution.
- When using peritoneal filter material, it is recommended that the filtration wind speed be ν≤2 m/min, or even ν≤1 m/min.
There is a misunderstanding in the industry that dust removal equipment is not considered the main equipment, and the purpose of installation is to meet environmental protection requirements.
In fact, the main function of dust collector pulse controller in grain and feed enterprises is to classify dust in key processes. The efficiency of dust removal equipment will directly affect the production volume of the enterprise.
Understand the general knowledge of pulse dust collectors and correctly understand the “selection” of reverse jet bag filters, and consider the design of air network and fan selection as a crucial factor in the entire dust removal system, so that pulse dust collectors can play a positive role in the grain and feed industry effect.
Precautions when using pulse dust collector
The dust collector is an important component of the technological process of the grain and feed processing plant. Its effect directly affects the normal operation of other equipment and the entire system.
Therefore, strengthening the operation and management of the dust collector to ensure the normal operation of the system becomes very important.
During the design and use process, we must also consider this characteristic of the dust collector when determining the inlet and outlet wind speed, filtration area, filtration speed, injection control parameters, number of solenoid valves, and compressed air consumption.
When the dust collector is connected to equipment with stable characteristics, such as: grain pits, belt conveyors, elevators, balers and other equipment.
Because the suction port is far away from the material layer, air is sucked directly from the atmosphere, and changes in the resistance coefficient of the dust collector have no influence on the changes in the output of these equipment.
The effectiveness of the dust collector mainly depends on the design and installation quality of the air net.
When the dust collector is connected to equipment that has strict requirements on air suction volume, such as crushers, pneumatic conveyors, air separators and other equipment.
These devices have strict requirements on air suction and have large air suction volumes. Therefore, when used in these occasions, the stability of the dust collector is very important.
In short, the dust collector is part of the process system in the grain and feed processing plant.
Only by carefully understanding the aerodynamic characteristics of various equipment connected to the dust collector can the dust collector be effectively and correctly operated and managed. (Find RICHI on YouTube)
